The hex color #305b6b, also known as Casal, presents some accessibility considerations, especially in web design. Its relatively low lightness value (approximately 35%) indicates that it can lack sufficient contrast against both pure white and pure black backgrounds. When used as text color, it's crucial to ensure a contrast ratio of at least 4.5:1 against the background, as recommended by WCAG (Web Content Accessibility Guidelines) for normal text. For larger text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Insufficient contrast can make content difficult to read for users with visual impairments. Tools like contrast checkers can accurately measure the contrast ratio between #305b6b and other colors to ensure accessibility compliance. When using #305b6b for interactive elements like buttons, ensure sufficient visual cues are provided to indicate state changes such as hover or focus. Additionally, avoid using color alone to convey important information, as colorblind users may not perceive the distinction.
